(fixed/updated 2016-05-10) Export your Google Music Library and Playlists (Google Play Music All Access) (see http://webapps.stackexchange.com/questions/50311/print-playlist-from-google-play-music for more)

export_google_music.js

// Jeremie Miserez <jeremie@miserez.org>, 2016
//
// A little bit of Javascript to let you export your Google Music library, playlists, and album track lists :)
//
// I posted this as an answer here: http://webapps.stackexchange.com/questions/50311/print-playlist-from-google-play-music
//
// 1. Go to: https://play.google.com/music/listen#/all (or your playlist)
//
// 2. Open a developer console (F12 for Chrome). Paste 
//    code below into the console.
//
// 3. All scraped songs are stored in the `allsongs` object
//    and a text version of the list is copied to the clipboard. I recommend running
//    `songsToText("all",true)` afterwards to get the full CSV information.
//
// 4. If you would like the output in a text format, can call
//    the songsToText() function. You can select a style, choose 
//    the format, and if only liked/thumbed up songs should be exported. 
//    The resulting list will then be pasted into the clipboard. 
//    Styles are ` all`, `artist`, `artistalbum`, `artistsong`, 
//    `artistalbumsong`. 
//    CSV will result in a CSV file and can be left out (defaults to false).
//    Likedonly can be left out (defaults to 
//    false) or set to true, and will filter all songs with 
//    ratings greater or equal to 5. 
//    E.g: 
//    - `songsToText("all",true,false)` will export all songs in csv format.
//    - `songsToText("all",true,true)` will export only liked songs in csv format.
//    - `songsToText("artistsong",false,false)` will export all songs as text.
//
// 5. You can then paste the data anywhere you like, for 
//    example http://www.ivyishere.org/ if you want to add the
//    songs or albums to your Spotify account. To make Ivy 
//    recognize full albums, use the "artistalbum" style. For 
//    songs, use the "artistsong" style.

Suggest to change

• allsongs[i].title
• allsongs[i].title.replace(/[\n\r!]/g, '').trim()

your variant gives me
Yelawolf - Love Story - !
Best Friend (feat. Eminem)
proposed is plain
Yelawolf - Love Story - Best Friend (feat. Eminem)

This script wasnt detecting when the page was scrolled to the bottom, it worked but it relied on the three second timeout.

Setting scrollDiv = document.querySelector("#mainContainer"); on #160 worked better for me.

I hope you dont mind, I modified the code so that it could be imported as a library and used it for the gplay exporting part of Portify.JS

Thank you very much for this script, I have been using it for months to track all my collection and see when the songs dissappear, and this is actually quite common.

Also, I noticed that from today that it doesn't work as Google play changed a little bit the layout. Would you be able to fix it? Thanks!

For some reason I get no notification when someone comments on here, so I'm sorry I didn't see your comments until today. I think this might be a Gist/Github bug? EDIT: Yes it's a Github bug.

@erapid: Thanks, done in Rev 19. Probably could do the same for artist/album/etc. if necessary.
@jordam: Thanks, replaced with your suggestion in Rev 19. Using the code: Sure, I see you even linked back to here in g-scrape.js so that's great.
@daviddgz: There is an issue with the copy() function it seems, but the scraping itself still seems to work. Run songsToText("all", false, false); once after the scraping is done, and it should work. I'll fix this issue though once I find what broke.

Also, I just noticed that the deduplication logic has a bug on the first pass. I'll fix that as well.

There seems to be no way to link to the diff of a Gist revision (?), so this is the best I can do:

• Rev 20: Deduplication issue fixed, diff:

Line 187:
-            seen[curr.id] = true;
+            seen[curr.dataid] = true;

• Rev 24: Scroll to top before starting to scrape.

Line 136:
+  document.querySelector("#mainContainer").scrollTop = 0; //scroll to top

• Rev 28: @davidggz "Fix" issue with script not working anymore: The copy() function only works on the developer console and not inside functions, it might be related to this bug. So as a workaround, you can either i) type in "copy(outText);" on the console manually (which works), or ii) copy the printed log output. This might be fixed in a future version of Chrome, then the copy should work automatically again.
• Rev 29: Fix CSV export (escape quotes and commas).
• Rev 30: Fix missing ratings and playcount.

As comment notifications don't work for Gists (as mentioned above) when people comment here, feel free to send me an email to jeremie@miserez.org or tweet me at @jmiserez after leaving a comment.

This is excellent!

Is this the right place to open an issue?
Possible bug: exported data has a letter 'E' in front of the song titles in case the song is marked 'explicit'.

@phpmoli: Yes this seems to be a bug, I'll see if I can fix it. All "explicit" songs have the string "E " (an E followed by two spaces) prepended to the song title.

Thank you for this!

You are a god

This is super!

Can you add track duration as an export option? It helps me match up songs.

Never mind, it's there in the CSV export.

The iron-scrolling-like breaks this badly

This doesn't work anymore. I guess it needs few fixes

It still works for me...? If you have more details please send me the error message/screenshot via email (jeremie@miserez.org).

This works well enough for me. There's some formatting issues but I think that's because of my library being weird (from uploading to GMusic years ago and having some old beta features enabled, like 5 star ratings). Thanks a bunch, I've tried other things in the past but none worked as well as this did.

This worked well for me.

Worked like a charm, thank you very much. Was also able to export playlists by executing the script while viewing them.

I just tried this on Chrome 57.0.2987.133 (64-bit) - Windows 10 and got this error:

Uncaught TypeError: Cannot set property 'scrollTop' of null
    at scrapeSongs (<anonymous>:103:54)
    at <anonymous>:177:1
scrapeSongs @ VM1962:103
(anonymous) @ VM1962:177

@itm1960 Just worked for me. Windows 10 / Chrome 57.0.2987.133 (64-bit)

Thanks for this, works great. Here's a small helper script I wrote to use the output of this to import albums into Spotify (https://github.com/brk3/gmusic-to-spotify)

This is fantastic. Thank you!

I am running into one problem--it looks like album names that end in an exclamation mark, are signifying the end of the list. e.g. This playlist has 50 songs, but will only export the first 36 to .CSV, presumably because the 37th song is from an album called "Climbing!"

https://play.google.com/music/listen#/pl/AMaBXykaDHfmXvAKqSyLc4z0PJxkIx5pZ7U-pjlx5iJaCxhczFfNTNX_DJ0oEMT8SNYs8pfvCKc5-KKj4qQX-uc_geXbifdTzA%3D%3D

Wow. Just googled for a luck and here it is. Thanks!

I just made very simple csv exporter to Tidal if anyone is interested. Everything needed is mentioned in comments in file. https://gist.github.com/RAZORzdenko/71801a20188e842ef03bed3b6d7a297f

How can I skip saving the album name?
